Filed: 1972-02-24
Abstract: 1382461 Expandable bobbin carrier MASCHINENFABRIK RIETER AG 24 Feb 1972 [27 Feb 1971] 8601/72 Heading D1J [Also in Division F2] A bobbin carrier comprises a support and a cap expandable to grip a bobbin tube, the cap being expanded when pushed onto the support by an elastic ring rolled, by the cap movement, from a groove in the support. The carrier may comprise, Figure 1, a support 1 having groove 5 initially accommodating a rubber ring 7, Figure 2, which is of circular cross-section when unstressed. The movement of cap 9, with bobbin tube 2, along support 1 causes cap taper 12 to push the ring from groove 5 onto the cylindrical support surface 6, thus outwardly deflecting the cap tongues 11, separated by slots, to grip the tube 2. When tube 2 engages support surface 4, ring 7 is located in cap groove 13a which may alternatively extend to the open cap end. The support and cap have projections 8, 14 which co-act to prevent easy cap removal. The distance between ring positions A and B is less than, but more than half, the circumference of the ring's cross-section, which feature is said to cause the ring when rolled to position B to bias tube 2 towards stop 3. The cap and wound package may be withdrawn, and the cap contracted, by manually pulling on cap hole, a cap handle or a key inserted in a cap hole, or by passing pressurised fluid through connection 25.

In a pilot controlled automatic volume control system, particularly for multi-channel carrier systems, e.g. of Specification 1,009,064; in which variations of the pilot signal level from a standard level in one direction or the other are detected by a respective one of two voltage discriminator two-state devices, e.g. Schmitt triggers, which control the stepping direction of a gain adjusting device including a thermistor, the effects of the back-lash, or hysteresis, in the operating potential of the voltage discriminator two-state device is reduced by feeding them via a temperature compensated comparison amplifier of relatively high gain. Fig. 1 shows an embodiment in which the rectified pilot voltage, applied to terminal Up, is compared with the voltage developed across Zener diode D 1  to control the input voltage to the low and high level voltage discriminator Schmitt trigger stages ST 1  and ST 2 . The arrangement is independent of temperature if the temperature coefficient of transistor Ts 1  is equal and opposite to that of diode D1. Alternatively the Zener diode may be connected in the base circuit of one of a pair of transistors connected as a differential amplifier with the rectified pilot signal applied to the base of the other transistor, Fig. 2 (not shown). An additional diode may be connected in one or the other base circuits of the differential amplifier to compensate the temperature coefficient of the pilot rectifying diode, Figs. 3 and 4 (not shown).

Filed: 1930-03-21
Abstract: 355,781. Furnace feed indicators. WECK, KOMMANDITGES. IN GREIZ, C. H., Dolan, Greiz, Germany. March 21, 1930, No. 9146. Convention date, March 21, 1929. [Class 51 (i).] To indicate and record the rate of coal feed to boiler furnaces the usual counter e driven in accordance with the speed of the travelling grate a and the depth of the fuel layer drives an indicating and recording mechanism through a mechanically-operated clutch which is periodically disengaged by clockwork to allow the mechanism to return to zero. A toothed integrating roller c driven by the travelling grate a meshes with a sliding gear wheel d adjusted on the roller in accordance with the setting of the slide b regulating the thickness of fuel, and the gear-wheel d drives the counter e. On the shaft f of the counter is fixed a toothed wheel g driving a wheel h connected through a clutch m with a pinion k driving a rack l with a marking pointer p recording on a drum o driven by clockwork n. The clutch m is disengaged once every three minutes by an escapement wheel q acting on a spring-pressed bell crank r adapted to displace the wheel h along its shaft, allowing the pointer p to drop to zero. The height of the vertical lines thus marked on the record strip shows the rate of fuel feed, and the strip may be graduated in terms of boiler output. The rack-and-pinion l, k may be replaced by a drum having a helical groove in which engages a sliding pointer. Fig. 5 shows a modification in which the counter e drives a second counter y through a clutch m2 which is disengaged by the clockwork n every three minutes. Before disengagement the lever r<3> acts on a bell crank z to cause an impression of the counter reading to be made on a record strip. A weight v<1> returns the counter y to zero on disengagement of the clutch m<2>. Specifications 11459/14, 206,189, and 247,573, [all in Class 106 (iv), Indicating &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the pointer is driven electrically from a make-and-break device on the shaft f of the counter. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to protective arrangements for alternating current systems
IPC: H02H3/30
Filed: 1924-04-10
Abstract: 236,656. British Thomson-Houston Co., Ltd., and Fitzgerald, A. S. April 10, 1924. Cut-out arrangements of the Merz-Price type employing protective' relays 16 connected in star between equipotential points 14 of the normallybalanced pilot-wire system 15 have each of the relays short-circuited by fuses 18 which constitute a delta-connection around the relays. By these means the sensitive relays are rendered insensitive to out of balance currents in the protected lines not due to a fault therein, whereas in the case of an earth fault an out of balance current circulates through the particular relay corresponding to the faulty line and through the neutral point 17, which is connected by the lead 13 to the neutral points of the current transformers 11, 11<1>, unaffected by the shunt fuses. In the case of an interphase fault a relatively large out-of-balance current will circulate through one or more of the fuses which will blow, thereby opening the short-circuit between two of the relays and permitting one or both of them to operate and isolate the section.
